ONE-WAY DRIVING MECHANISM.

'Application lcd March 3, 1927, Serial No. 172,485, and in Belgium March 9, 1926.

' This invention relates to mechanisms, aiid is use in connection wit one-way driving especially adapted for h variable speed power the desired speed to driven member. The one-way be transmitted to the driving mechanism according to the present invention is of the type wherein the driving and driven members have track `members disposed in relation that are eccentrically to eachother and between which are wedged sets of balls of different diameters.

According to the present invention, these balls are spaced apart and held at definite points between the track members by means of springs.

This above construction is particularly` applicable to one-way driving mechanisms in which a power is transmitted to the drive i by a single oscilla-ting member.

' vtric track (2o-operating with a track of the each locking disc being'rigidly the driven shaft of balls wedged between each of eccentric tracks, said balls being the course of descri `In or for mechanism in which power is transmitted from a pluralit members, there are provide of oscillating a plurality of vdriving members mounted concentrically to each other, each having eccentric tracks, a driven member mounted concentrically to the driving members, and having a track member comprising a plurality of eccentric tracks cti-operating with the eccentric tracks on the driving members, wedged between .eccentric tracks, sai

and sets of` balls each of the co-operatiiig d balls being spaced apart and held at definite points between the cO-Operating tracks by means of springs. i 'l The invention may ity of independent driving members mounted side by side around the driven member, each driving-member being actuated separately by a driving rod and having an eccenlocking disc,

secured to eratin Aspace apart and hel also comprise a pluralproper, and sets the co-opd at definite points between the co-operating tracks by means of springs.

illustrating several Figure 1 is a cross constructions.

-section through a oneway driving mechanism driven by a. single driving member, taken on line I--I of Figure Q,

Figure :2 is a longitudinal section through the same mechanism, on line'II-II of Figure 1.

Figure is a longitudinal section through an analogous mechanism driven by meansl of two cranks.

Figure l is a longitudinal section through, another constructional form of a mechanism driven by means of three cranks. s

Referring to Figures 1 and 2, it will be seen that the mechanism comprises a shaft 1 bearing a disc 16, the peripheral surface ot' which has a groove 17 which forms a rolling track for balls 18 arranged between the said rolling track or race 17 and another rolling track 19 provided in segments 20, the inner surface of which segments is eccentric relatively to the rest of the mechanism. These segments 20 are iiXed by anyv desired means. for instance, by screws 21, to a drum 22 which is keyed to the driven shaft 14 proper.

The characteristic of this device is that when the mechanism is actuated by an oscillator 2, operated by a driving rod 4, the

.driving is effected by the series of balls 18 tors. A portion of the mechanism is constructed in the sam'e way as in the case of a single oscillator. The various elements of this portion have the same vreference numbers as in the case already described.

The second oscillator2, which is actuated by rod 4 drives the drum`22 by means of an intermediate disc 16 secured to a sleeve 26 concentric with the shaft 1.

It will be readily understood how the driving mechanism in a single direction operates in the case of more than two cranks. It is only necessary to increase' the number ofu sleeves 26 concentric with the shaft 1.

It may also be replaced by a device in Which, unlike that hereinbefore described, the driving device is outside the transmission or driven device (Fig. 4). Such a dcvice is shown by Figure 4 which represents three locking discs 16, 16 and 16" secured to the drivenshaft 14 proper and three eccentric rings 20, 20', 20 independent of one another, each of these rings being actuated by an associated driving rod 4, 4or 4, Locking balls 18, 18', 18 are ldisposed between thc discs and the eccentric rings.

This construction, .among other things, avoids the multiplicity ofbushes connectingl at present the driving cranks vto the locking discs in the event of several driving connecting cranks being used.

Obviously, the invention may `also be applied in the case in which the transmission is effected by more than two or three cranks, the examples given in the foregoing being merely by way of illustrationl and not limitative.

What we claim is:

A one-Way driving mechanism comprising driving and driven members having track members eccentrically disposed relatively to eachother, and sets of balls of different diameters wedged between the eccentrically disposed track members, said balls being spaced apart and held at definite points between the track members by means of springs.

VIn testimony 'whereof We aix our signatures.
